Metric & Imperial setup blocks

I could not find a complete set of workshop setup blocks so I made my own.

These are generated parametrically from the included openscad design and python script to run through the different sizes and generate the style files.  I've included the most commonly used sizes in both metric and imperial, but it would be easy to modify the python script to add more if you need them.  Note that the embossed text has a depth of 0.5mm.
